The aim of this proposal is to develop novel mixed-dimensional 2D/0D heterostructures based on halide and chalcogenide nanomaterials to construct a highly efficient solution-processing platform for short wave infrared detection. Moreover, innovative low-dose transmission electron microscopy and spectroscopy will be applied to unveil the fundamental structure-property relationship and fill the gap of knowledge for these materials. Such mixed-dimensional nano-heterostructures combining 2D halide perovskites with 0D quantum dots with complementary physical properties and atomically resolved interfaces will significantly enhance the performance, thereby enabling breakthroughs in a broad range of disruptive optoelectronic technologies.
